Abstract
BACKGROUND:
Consideration of cost determinants is crucial to inform delivery of public vaccination programs.
OBJECTIVES:
To estimate the average total cost of laboratory-confirmed influenza requiring hospitalization in Canadians prior to, during, and 30 days following discharge. To analyze effects of patient/disease characteristics, treatment, and regional differences in costs.
METHODS:
Study utilized previously recorded clinical characteristics, resource use, and outcomes of laboratory-confirmed influenza patients admitted to hospitals in the Serious Outcomes Surveillance (SOS), Canadian Immunization Research Network (CIRN), from 2010/11 - 2012/13. Unit costs including hospital overheads were linked to inpatient/outpatient resource utilization before and after admissions.
RESULTS:
Dataset included 2,943 adult admissions to 17 SOS Network hospitals, 24 Toronto Invasive Bacterial Disease Network hospitals. Mean age was 69.5 years. Average hospital stay was 10.8 days (95% CI: 10.3, 11.3), general ward stays were 9.4 days (95% CI: 9.0, 9.8) and ICU stays were 9.8 days (95% CI: 8.6, 11.1) for the 14% of patients admitted to the ICU. Average cost per case was $14,612 CAD (95% CI: $13,852, $15,372) including $133 (95% CI: $116, $150) for medical care prior to admission, $14,031 (95% CI: $13,295, $14,768) during initial hospital stay, $447 (95% CI: $271, $624) post-discharge, including readmission within 30 days.
CONCLUSION:
The cost of laboratory-confirmed influenza was higher than previous estimates, driven mostly by length of stay and analyzing only laboratory-confirmed influenza cases. The true per patient cost of influenza-related hospitalization has been underestimated and prevention programs should be evaluated in this context. This article is protected by copyright.
